This is an exercise on Thermometric scales.
We have as data:
We apply the following formula:

We substitute data in the formula:

First multiply 9 x 220, then the result of this division is divided by 5.

Therefore the cake recipe that should be baked at 220 °C for 45 minutes, on the Fahrenteir scale is 428 °F. Which indicates that it will be very hot.
Answer:
12641680.
Step-by-step explanation:
Answer:
3 hours
Step-by-step explanation:
Since the speed is remaining the same, time is proportional to distance, so you have ...
1.75 hours/(70 miles) = (additional hours)/(120 miles)
Multiply by 120 to find the additional hours:
additional hours = (120/70)·(1.75 hours) = 3 hours
_____
Units of miles cancel from numerator and denominator of (120 miles)/(70 miles).
